Technical field
The present invention relates to stainless steel surface processing technology field, be specially a kind of stainless steel electrolytic polishing fluid formula and technique.
Background technology
Electropolishing also claims electropolishing, it is the electrochemical dissolution phenomenon utilizing anode to produce in electrolyzer, make microscopic protrusions part generation selective dissolution on anode to form the method for smooth-flat-surface, it is a complicated anode oxidation process, along with dissolving and the oxidation of workpiece surface, but be different from anodic oxidation.
Stainless electropolishing solution, general all based on phosphate solution and phosphoric acid, sulfuric acid is auxiliary, add some additives to be again made, and the material concentration of phosphoric acid and sulfuric acid and ratio requirement are determined according to wanted polishing workpiece, its controling parameters of simultaneously different polishing fluids is different, and the conservative control of temperature, current density, polishing time plays vital effect to final polishing effect.
The present invention is mainly for 304 and the stainless surface treatment of 420 class number, and provide one electropolishing liquid formula targetedly, it mainly solves the problem that existing stainless steel electrolytic polishing fluid contains the harmful ions such as chromium.
Summary of the invention
The present invention for the technical problem that solves for providing a kind of stainless steel electrolytic polishing fluid formula and technique, it is for solving 304 and No. 420 stainless surface treatment problems, it selects phosphoric acid and sulfuric acid to be basic raw material, and add a certain proportion of brightening agent, its temperature of conservative control, current density, voltage correlation parameter, thus can realize the polishing effect of high light, and the long period that electrolytic solution can reach 2 years changes the groove phase.
Technical solution problem of the present invention adopts following technical scheme:
A kind of stainless steel electrolytic polishing fluid formula, it is characterized in that: its phosphoric acid, sulfuric acid and by diethylmethyl methyl alcohol, Soxylat A 25-7, the brightener of polypropylene glycerol aether composition, TXD110 brightening agent, the mass percent of described phosphoric acid is 51-55%, proportion is 1.70, content is 85%, the mass percent of described sulfuric acid is 42-46%, proportion is 1.84, content is 98%, described brightener mass percent is 3%, proportion is 1.05-1.15%, the diethylmethyl methyl alcohol of described brightener, Soxylat A 25-7, polypropylene glycerol aether proportioning is 1:1.5:0.03.
